The story begins when Li Zhou was diagnosed with a heart disease. When he was a child, Jiang Mu accompanied him and played with him every day. "Brother Jiang Mu promised me that we will be best friends!" Li Zhou looked at Jiang Mu with a pure face.
A few days after saying this, Jiang Mu left Li Zhou due to personal matters.
When they met, Li Zhou forgot that the person in front of him was his best friend, and Jiang Mu vowed not to leave him this time after seeing Li Zhou.
Perhaps God didn't want to see them have a happy ending. Li Zhou left Jiang Mu forever due to a sudden heart attack.
"Hello, Jiang Mu
I never thought you would receive a letter from me..."
Intention: I want to live forever because of you
